Question about wood!

Is there a big difference between designated tone-wood and random wood?

Like, would the difference between a designated guitar body-blank in mahogany and a random piece of mahogany from an old table/bought in random woodstore/found in a shed/etc be big?

Im asking this because Im looking to start my first guitar build and my dad can probably fetch me some woods of different kinds from various places for free, so I wanna know if I should use this wood, or just go ahead and use the 90£ on designated tone-wood

You CAN play anything with anything....but some guitars sound right for some things, and not for others. Single coils sound retarded for metal, though those who are apeshit about harpsichord probably beg to differ.
